I saw this and I thought Eureka!!! About two years after getting my discontinued BTC5090 I can get what looks like an identical keyboard which I can then use for my Theater room leaving the older keyboard in the family room.
I search the web and find glowing reviews (the handles by the way are a great touch for a keyboard like this used for a home theater coach/lap situation.Very convenient for picking up and passing to other/setting down etc.
Problem is there still appears to be no place you can actually buy one in the US either.
But since the reviews were dated in the last couple days I imagine its just a shipping delay and they will be available shortly.
Iintend to get one - from the reviews it has an even better range than my 5090 (one reviewer mentioned going outside the house with it still working)
